What is Colitis?

Colitis, as the name suggests, is the inflammation of the colon. The colon can also be called the lower or the larger intestine, and this is where stools are stored, water is absorbed, and further digestion happens. While it’s easy to prevent and treat, colitis can actually be a symptom of a health issue that’s more serious which may require another form of treatment.

If they are experiencing colitis because of a grain allergy, then you can look into providing them with a grain-free option, which you can find among the top dog food brands.

Causes of Colitis


Colitis can manifest when your dog is stressed, and there are a variety of reasons how this could happen. Some of the more common reasons is traveling, moving, or a home upheaval. A change in scenery is not always comfortable for our dogs, and their distress may manifest as a health concern like colitis. If you suspect that stress is the reason why your dog has been exhibiting symptoms of colitis, then you can help them by supporting them throughout the stressful event. Making your dog feel safe and comfortable can help them relax throughout the otherwise stressful event and if that doesn’t work, you can give them some probiotic supplements in order to relieve their symptoms.

Parasites or Infections

If your dog has been licking or eating from the ground a lot (which, knowing dogs, is very likely), then they may unknowingly pick up some parasites or infections that can affect their gut. And if this happens, then they may present themselves through colitis. These infections and parasites may include, but are not limited to, E.coli, Salmonella, and whipworms. You can reduce the risk of this happening by bringing a portable water bowl that your dog can drink from during a walk. Your veterinarian can help you address these parasites and infections by diagnosing what infected your dog through a stool sample and then prescribing the according treatment and medicine.


Dogs can get allergies too, and if they are exposed to allergens in the home, outdoors, or even from their food, then they can also have colitis. If this is the case, you can seek help from your vet in order to determine what your dog is allergic to through a process of elimination. Afterwards, you can change their diet or their environment accordingly.


If the reason does not seem to be any of the above, then it’s probably another disease that is affecting your dog’s colon and bowels. You may be made aware of its presence when none of the other plausible reasons is diagnosed as the reason for your dog’s colitis.


Changing your dog’s diet may aid in relieving their colitis, but remember to check on the larger problem that could be causing the colitis. You can ask help from your veterinarian in order to pinpoint the exact reason why they’re experiencing colitis in order for you to take the appropriate measures in relieving your dog.
